Increased structural integrity with structural foam

[hotroddr]

it prevents rust, lowers noise, makes the body flex less by spreading the loads over a greater area and increases safety. I read about one roll over test where the top of the vehicle initially caved in 14". After they filled the pillars with the structural foam it only caved in 3" in the roll over test. Thats pretty impressive if you ask me.
My fiance works at a body shop and she checked with her supply manager, and for 2 part set it is $22. I am not sure how much this will do but I know I can get the stuff now and I am going to try it.
There are different kinds of foam used in new vehicles, structural and noise dampening. The structural foam expands about 3X and the regular noise dampening foam expands around 10X the volume you apply. This is according to what I have read. I have not used the stuff yet so I cant say from experience. I have used great stuff expandable foam in the structure in my trunk on my 68 firebird and it was amazing how much noise it killed, so I have to believe this other stuff works too.
